A control device (50) wherein a calculation unit (52) calculates an estimated interference area for a base station the installation of which is planned in a second system, said calculation being made on the basis of the planned installation location of the base station the installation of which is planned, and the installation location of a reference base station in the secondary system, and the actual measured interference area of the reference base station. An identification unit (54) identifies a frequency channel which is in a first system and the usage area of which does not overlap the estimated interference area calculated by the calculation unit (52). For example, the calculation unit (52) calculates an expansion value on the basis of parameters that include the divergence relationship between the planned installation location and the installation location of the reference base station, and then uses the calculated expansion value to expand the interference area of the reference base station, thereby calculating the estimated interference area. |
